I recently acquired a 1972 model 413 industrial engine supposedly out of a dump truck. A few things I found on this engine have me wondering...
Some on the internet say these 413 "cold weather" blocks are just under-bored 440s, so you can supposedly take them out to 4.32" or + .060" possibly from there. I know I need to get it sonic checked, but has anyone verified this?
All I've read online says these came w/ gear drives and reverse rotating cams...this one has a double roller chain in it. Wonder if it has been gone through before or if it came this way?
Are these big cylinder heads and related parts (water pump setup) worth anything or should I just send em to the scrapyard? The shortblock is staying with me...especially since it has a forged crank (which is a 6 bolt flange). I have the short tail w/ drum brake 727 too.
I thought the heat shields b/t the block and exhaust manifolds were interesting.

I was planning on keeping it for myself since, like you said, using a 413 industrial motor for a buildup isn't what a lot of folks like to hear. It's a '72 model. I actually got a package deal...three 440s and this 413, all four w/ 727s attached. Too good a deal to pass up...guy was moving out of state and couldn't take them w/ him. Was a lot of fun loading these heavy suckers under a shed w/ a soft dirt floor using a cheap flimsy harbor freight engine hoist.
I won't likely tear it apart anytime soon. Well, except to remove the topend. Wipe some grease on the bores, wrap it up, and stick it on a pallet in the barn to save for a later date.

Can you show a close up picture of the spark plugs on these heads. They appear to be laid out like a 340 instead of the normal 383/440 style. Or maybe it is just the picture that makes them look at an angle and pointing up instead of from a 90 degree side. Curious about the heads. What do the ports and chambers look like. The manifolds appear to bolt on differently.

als499...I hear getting Stage V to make a set of those conversion heads is a challenge. You're right though, about the shortblock at least. You can find old school std. bore hemi pistons cheap.
Scatpack...they do point up and slightly in like a small block. These heads are different than normal BB heads w/ the extra extended water jackets around the exhaust ports...hence the manifolds bolting on differently. The intake bolts on the same and will work on standard heads so I'm told. They have sodium filled valves. The head is taller which means longer pushrods. The rockers look the same, but supposed to be different somehow. I have not pulled a head off yet, but will post some pics when I do if you'd like.
Transman...got it UP to 5.5 mpg??? Wow, lol.

I'm assembling a 1973 413 truck block now that I took in trade on assembling a customers pump gas pickup 440 motor that he had bought all the parts for the short block. I sonic tested the 413 block and it was no where thick enough to bore to 4.320 safely I had it bored to 4.250 and added a used Mopar brand 4.15 stroke crankshaft with the 2.375 rod journal sizes so I can put it in my 1963 Plymouth pump gas street car in the near futre, hopefully This will be one of my old school junk parts build using a set of used 440 source heads that I took in trade, a set of custom Auto Teck pistons, a used set of Eagle Hemi rods with the big pins and so on I did reuse the crankshaft, I had it offset ground to BB Chevy rod sizes to 3.90 stroke for another pump gas build using a late model 440 block out of another 440 motor home take out I think the misinformation on those older 413 truck blocks was put on the internet by a keyboard "expert" I've sonic tested several of them (5+) and none of them where extra thick on the bores The biggest I had any of them bored to was 4.250.

IF you don't care, post up some pictures of the spark plugs and combustion chamber. I am intrigued by that design. Never ever saw it before. And I thought I had worked on every Mopar block ever made.

Cab...thanks for the heads up! I will definitely have it sonic checked before having it bored. Like anything else, there's a lot of conflicting info out there about these things. Probably b/c there aren't a lot of them around and most is hearsay. Read where these are supposed to have the 6 pack rods...this one has LYs.
SCATPACK...I'll get some more pics for sure. Hope to get the heads off of it the end of the week when I have some free time. Guess I'll run a craigslist ad for a few weeks to see if anyone wants the heads and stuff. If not, off to the melting pot they go. This stuff is so heavy it won't be worth shipping anywhere. Just the water pump weighs a ton.
dodger mope...lots of those type machines running around here, but all diesel. I'm sure they're all newer than what this would have been in though.
cudaman...I have not removed the shields yet, but there does appear to be more stiffening ribs on the side of this block. That's why I referred to it as a "cold weather" block, which is what I usually see them called here on Moparts.

The vast majority of those came in motor home chassis. They were all automatics, the manual trans version is not as common as the auto for that reason even though most of the non motorhome apps were manual trans equiped.
The heads flow worse than a run of the mill SB head. Chambers look sorta like a 516 BB head but with tiny valves and huge space between the valves.

I post this as a question and a response. We run a 413 block in our '63 N/SS Plymouth. It's bored .060 to make it 426". It is an industrial block with the extra webbing on the sides. Otherwise it's been built as a race engine from back in the day...12.2:1, Max Wedge heads and intake, two Carter 750's, and a big roller cam. The car runs in the 10.90 range.
That being said, my father and I got into a discussion just yesterday when I told someone that our engine was a 413 + .060. He said, "No, it's a 426!" If I remember correctly, weren't the '62 and early '63 cars 413's? I believe in mid '63 they went to 426". My question is, was the 426 a new casting, or were they 413's that were over-bored? Thank you in advance.

i built a very mild street "440" for a guy, that turned out to be a 413 industrial punched out to 4.32. that thing had SCARY thin cylinder walls. it's still out there melting tires, but he is lucky in most all of his endeavors. i don't have any sonic numbers, i just felt the "thickness" by sticking a pinky into a water jacket hole. compared to a few other blocks i had laying around, it was downright frightening. good luck, is all i can say...
for what is the good life if not doing things thoughtfully?

When my dad still had the salvage , we use to get a lot of PA state trucks, the only gear drive 413 we found came out of a 68(?) C800. all the others were chain.
